Par*_*nak 232 html php combobox html-table drop-down-menu
我有一个html表单,其中有一个选择列表框,您可以从中选择多个值,因为它的multiple属性设置为multiple.考虑形式方法是'GET'.表单的html代码如下:
<html>
<head>
<title>Untitled Document</title>
</head>
<body>
<form id="form1" name="form1" method="get" action="display.php">
<table width="300" border="1">
<tr>
<td><label>Multiple Selection </label> </td>
<td><select name="select2" size="3" multiple="multiple" tabindex="1">
<option value="11">eleven</option>
<option value="12">twelve</option>
<option value="13">thirette</option>
<option value="14">fourteen</option>
<option value="15">fifteen</option>
<option value="16">sixteen</option>
<option value="17">seventeen</option>
<option value="18">eighteen</option>
<option value="19">nineteen</option>
<option value="20">twenty</option>
</select>
</td>
</tr>
<tr>
<td> </td>
<td><input type="submit" name="Submit" value="Submit" tabindex="2" /></td>
</tr>
</table>
</form>
</body>
</html>我想在display.php页面的选择列表框中显示所选值.那么如何使用$_GET[]数组在display.php页面上访问所选值.

如果您希望将PHP $_GET['select2']视为一个选项数组,只需在select元素的名称中添加方括号,如下所示:<select name="select2[]" multiple …
然后,您可以在PHP脚本中访问该数组
<?php
header("Content-Type: text/plain");
foreach ($_GET['select2'] as $selectedOption)
echo $selectedOption."\n";
$_GET$_POST取决于<form method="…"价值,可以代替.

更改:
<select name="select2" ...
至:
<select name="select2[]" ...

使用以下程序从选择框中选择多个值.
multi.php
<?php
print <<<_HTML_
<html>
<body>
<form method="post" action="value.php">
<select name="flower[ ]" multiple>
<option value="flower">FLOWER</option>
<option value="rose">ROSE</option>
<option value="lilly">LILLY</option>
<option value="jasmine">JASMINE</option>
<option value="lotus">LOTUS</option>
<option value="tulips">TULIPS</option>
</select>
<input type="submit" name="submit" value=Submit>
</form>
</body>
</html>
_HTML_
?>
value.php
<?php
foreach ($_POST['flower'] as $names)
{
print "You are selected $names<br/>";
}
?>

您可以使用此代码从多个选择组合框中检索值
HTML:
<form action="c3.php" method="post">
<select name="ary[]" multiple="multiple">
<option value="Option 1" >Option 1</option>
<option value="Option 2">Option 2</option>
<option value="Option 3">Option 3</option>
<option value="Option 4">Option 4</option>
<option value="Option 5">Option 5</option>
</select>
<input type="submit">
</form>
PHP:
<?php
$values = $_POST['ary'];
foreach ($values as $a){
echo $a;
}
?>
<html>
<head>
<title>Untitled Document</title>
</head>
<body>
<form id="form1" name="form1" method="get" action="display.php">
<table width="300" border="1">
<tr>
<td><label>Multiple Selection </label> </td>
<td><select name="select2[]" size="3" multiple="multiple" tabindex="1">
<option value="11">eleven</option>
<option value="12">twelve</option>
<option value="13">thirette</option>
<option value="14">fourteen</option>
<option value="15">fifteen</option>
<option value="16">sixteen</option>
<option value="17">seventeen</option>
<option value="18">eighteen</option>
<option value="19">nineteen</option>
<option value="20">twenty</option>
</select>
</td>
</tr>
<tr>
<td> </td>
<td><input type="submit" name="Submit" value="Submit" tabindex="2" /></td>
</tr>
</table>
</form>
</body>
</html>
您可以像这样直接迭代它
foreach ($_GET['select2'] as $value)
echo $value."\n";
或者你可以这样做
$selectvalue=$_GET['select2'];
foreach ($selectvalue as $value)
echo $value."\n";

这将显示所选值:
<?php
if ($_POST) {
foreach($_POST['select2'] as $selected) {
echo $selected."<br>";
}
}
?>
// CHANGE name="select2" TO name="select2[]" THEN
<?php
$mySelection = $_GET['select2'];
$nSelection = count($MySelection);
for($i=0; $i < $nSelection; $i++)
{
$numberVal = $MySelection[$i];
if ($numberVal == "11"){
echo("Eleven");
}
else if ($numberVal == "12"){
echo("Twelve");
}
...
...
}
?>
